Interpretation of gravity and magnetic data with geological constraints for 3D structure of the Thuringian Basin, Germany
Original language description
We apply our novel methodology for separation of potential field sources and their 3D inversion to a large area (Thuringian Basin in central Germany). Gravity and magnetic data are separated into long, medium and short wavelengths which are inverted separately. Our main goal is to study uniqueness of the solution and its stability in all steps of the interpretation process and to demonstrate, how geological constraints can diminish degree of non-uniqueness by interpretation of gravity and magnetic anomalies. Our numerical experiments with medium wavelengths show, that if we explain negative anomalies with topography of near-surface layers, the obtained solution is not supported by borehole data. This is why we explain them with restricted bodies (granitic intrusions) at the depths between 4 and 10 km. They are located above a density interface with topography at the depth of approximately 10 km. 3D inversion of magnetic data (short wavelengths) allows investigating of fine structure for the upper boundary of the crystalline basement: two uplifts in the depths between 2 and 0.7 km are found. By using the residual negative anomalies we study salt tectonics: geometry of a salt pillow with the thickness of approximately 200 m is obtained which is in the good agreement with borehole data.
